Check out this beauty. Designed by Ana Mestre, a Portuguese furniture designer, the Lagarta stool is made from agglomerated expanded cork, the most sustainable kind of cork composites. There’s a hollow in each stool, allowing them to nest together for infinite modular seating. At a price of $345, it’s just under the cost of the Cork Stool by Jasper Morrison for Moooi.

Note: While there doesn’t seem to be a ‘buy it now’ function on the site of Corque Design, the NY Times lists Esporão (420 West 14th Street (Washington Street)) as a retailer: (212) 929-8515.
